a team of 4 golfers scored 69,73,70, and 74 on the first round on a par 72 course. they reduced their team score by 3 on the second round.

a) How many strokes above or below par was the team score on the first round?

b) How many strokes about or below par was the team score on the scond round?

I don't understand these questions. help plz and thank you :)

a) Add the four scores to find the total score. Then divide by 4 to find the average score. Compare it with 72.

b) Subtract 3 from the team's total score to find the total on the second round. Divide by 4 and compare with 72.
